Embodiment Construction

[0040] Refer to attached Figure 1-8 :

[0041] The manufacturing method of vehicle of the present invention, comprises the steps:

[0042] 1. Making an injection mold of a plastic vehicle, the mold having the overall shape of the vehicle;

[0043] 2. Inject plastic and gas into the feeding barrel 1, heat and stir with the screw 12 to melt the aforementioned plastic and mix with the aforementioned gas to form a mixed foamed plastic melt;

[0044] 3. Introduce the aforementioned mixed foamed plastic melt into the first storage barrel 2;

[0045] 4. Extrude the plastic melt with a capacity suitable for one shot out of the first accumulator barrel 2, and at the same time perform pressure control and compensation in the cavity of the first accumulator barrel 2 to maintain the first accumulator barrel 2. Stable pressure in the 2 cavities of the storage barrel;

[0046]5. The plastic melt that is pressed out of the first storage barrel 2 is introduced into the second storage bar...

Abstract

The invention relates to a method for manufacturing a vehicle, which comprises the following steps: manufacturing an injection mold of a plastic vehicle; preparing a mixed formed plastic molten liquid; leading the molten liquid into a first material storage barrel; pressing the molten liquid out of the first material storage barrel; leading the molten liquid into a jetting barrel through a first check valve; at the same time, supplementing materials to the first material storage barrel by a feeding barrel; pressurizing the jetting barrel so as to jet the molten liquid to a mold for molding; making the surface of the plastic molten liquid cool first, and measuring the current jetting quantity of the jetting barrel and the current output speed of the feeding barrel; and adjusting the output speed of the feeding barrel, adjusting the rotating speed of a screw rod on the feeding barrel so as to control the feeding speed of plastics; at the same time, adjusting the inlet air speed so as to match the plastic feeding speed. The vehicle which is manufactured according to the method comprises an outer layer which does not contain bubbles or contains a small amount of the bubbles and an inner core which contains the bubbles, and the inner core is coated by the outer layer.

Description

technical field [0001] The invention relates to a method for manufacturing plastic locomotive parts and its products. Background technique [0002] Known motorcycle parts, such as instrument panels, interior trim panels, bumpers, tires, car mats, motorcycle handles, etc., are mostly made of pure plastic by injection molding, which consumes more plastic. Prices are high and people are eager to save on raw materials. In addition, pure plastic products have poor impact resistance, and when used as locomotive components, they are prone to cracking or even breaking due to collisions, resulting in damage. [0003] The use of foamed plastics to manufacture locomotive parts does not affect its use, and can significantly save raw materials, and the foamed plastics have good impact resistance, which can make locomotive parts durable and reduce weight. However, the known technology of foamed plastics is not suitable for the manufacture of automotive parts. [0004] The conventional ...
